Specification of Letters Patent;

Patented Feb. 17, 1920.

Application filed February 10, 1919. Serial No. 276,030.

To all whom it may concern:

Be it known that I, WALTER L. MAJORS, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Oil-Stoves, of which the following is a specification.

.Set forth in the claims.

In the accompanying drawings vforming part of this specification, inwhich like numbers of reference denote like parts wherever theyv occur,

Figure 1 is a side elevation lookingat the oil tank and burner casing of the device of this invention, one of the forms of remov- 1 able heater covers being shown in place; and

Fig. 2 is a vertical sectional view of Fig. 1, with the heater cover removed.

Any, suitable fuel oil 1, supplied under pressure from any suitable source, such, for.

instance, as reservoir tank 2, is conveyed under pressure through filter chamber 3, which chamber, with any'suitable filtering medium adapted for permitting oil .to flow therethrough, but tending to obstruct the passage of and retain foreign substances in the oil, particularly such as are not in solu tion, thence through tube 4 and auxiliary filter chamber 5, which is also provided with a filtering medium of any suitable character, thence through tube 6 to coil- 7 or the like, where said oil is vaporized, as hereinafter described, said vaporized oil flowing from coil 7 to burner 8,. Tank 2 may have an oil inlet 9 provided with plug 10 or the like, and the oil 1 in tank 2 may be placed under pressure by any suitable means, such, for instance, as by. means of hand-operated air compressor 11 of well-known construction adapted to communicate with the interior of tank 2 above normal oil surface level by means of valve 12 of well-known construction. For conveniently shutting off and for regulating or controlling the flow of oil from tank 1 to coil 7 a valve, such, for instance, as needle-valve 13, may be provided in operative connection with any suitable part of the oil supply line, it being of course, understood that either or both filter chambers 3 and 5 may be provided in said oil line, or additional filter chambers, not shown, may be provided in said oil line.

Casing l l'may be mounted on oiltank 2, as shown in the drawings, and a plurality of bolts 15 may be provided, said bolts being adapted to connect said casing and said tank firmly together, the heads of said bolts being adjacent the under side of flange 16 borne by the reinforcement 17, and the screw-threaded ends of said bolts extending through appropriate holes in flange 18 forming the upper rim of casing 14, nuts 19 being adapted for the well-known purpose of conveniently assembling and disassembling the parts associated together by means of the said bolts, said bolts being adapted intermediate their ends to be mounted, as shown in Fig. 1, through appropriate openings in flange 20 borne by the bottom of casing 14. A spacing casing 21 may be pro vided, mounted on the portion of each bolt 15 intermediate flange 18 and flange 20.

Spider 22 may have flanged rim 23 adapted to seat on shoulder 24 of flange 18, to support the spider in the top of caslng 14, as best seen in Fig. 2, internally screwthreaded sleeve 25, axially borne by spider 22, being adapted to engage one end of screw-threaded pin 26, the other end of said pin bearing a screw head 27, which head is adapted to engage the under side of centrally-bored flame-buffer disk or plate 28, upon which plate is mounted buffer body 29, said buffer body being appropriately bored to permit the head end of pin 26 to be mounted-'therethrough, as shown in Fi 2. Vaporizing coil 7 may be a spiral coi, as shown in the drawing, and is so disposed that bufler plate 28 and buffer body 29 may be adjusted a desired spaced relation to burner 8, by means of adjusting screwthreaded pin 26 in sleeve 25, upwardly and downwardly between the space surrounded circumferentially by the convolutlons of said coil, the jet outlet of burner 80 b'elng disposed substantially axially of said c rcumferentially surrounded space and below same and substantially on a line with the axial center of said sleeve and said plate 28'when the parts are mounted in operative position shown in, F 1g. 2.

The-operation of the device thus' far described may now be explained, Tank 2 h-aving been partially filled with fuel oil 1 through intake 9", and plug or valve 101 hav-v ing been adjusted to closing;positionwiniiir take 9, air pumpil l may be operated to force air, into tank2- to exert any desired pressureag'ainst oil-1'1 in. sald tank 2, and, under sald 'pressul'e,,oil will pass from tank; 2 up 1 casing 14', each of whichidoor; openingszmay through. filter 3. to valve 13, and, said valve having-been moved to any-adjusted open'position, the, oil will flowj'thence to. auxiliary filter 5, thence to .coil v .7 and intobnrnenS, whereupon the flame 015 a torch or the like 'having beeii applied to said burner and coil through eitheroti two door openingsfiii in be provided with. a sliding doori34reoiiiwell= known construction, said torch flame-.or; the like-will initially'volatilize oil: insa'id burner:

8&and' said coil'T, and ignite said'volatilized oil-as; same escapes) through jiet opening; 30 insaid burner. The: torch flame maythen be withdrawn, and, louder plate218; and bufier body 29 borne thereby havingbeenad'-v justed to a suitable distance fromjburner 8, to establish satisfactory conditions; :Eor efliective combustion ofvolatilized oil ignited at jet opening 30, the heat of said combustion will volatilize more'oil as sameflows under pressure into the coil, thus. automatically continuing the-supply 0t volatilized: oilto the burner for-combustion at jet opening 30 long as valve 13 is inopen position andas long as; oil flowsto' said? coil under pressure from the source of oil supply; Moreover, while burner- 8 functions and combustion thereat continues, the resulting: heat within casing 134 tends to radiate to the compressed airr-and the oil! in tank 2, thus; heatinga both odors-so common in many: oil-burning de-:

vices; y It will: be observedthat plate 2 8andbody' said feed pipe,

29 comprise afiame bulier piece in two parts,

and this constructionsubstantially adds radiating surface for radiating heat from said bufiier piece, as a very slight air space is provided between said plate 28 and said body 29, whereby the advantage is obtained that the plate 28", having less volume than body 29, is heated first, and quickly provides radiation to assist in volatilizing-oil in coil 7. Having thus described this invent on l hereby reserve the benefit of all' changes in form, arrangement, order, or use of parts, as it is evident that many minor changes may be made thereinwithout departing-horn the spirit on this invention or the-scope of the followin-g claims.
